Chronic low back pain and postural instability: interaction effects of pain severity, age, BMI, and disability.

ABSTRACT:

Objectives

This study aimed to (1) compare postural sway patterns between individuals with chronic low back pain (CLBP) and asymptomatic controls, (2) evaluate correlations between pain severity and postural stability variables, and (3) assess the interaction effects of age, BMI, pain severity, and disability on postural stability under eyes-open and eyes-closed conditions.

Methods

Postural stability (sway area, sway velocity, CoP displacement) was assessed in 88 CLBP patients and 88 controls using a stabilometric platform. Pain severity (VAS) and disability (ODI) were recorded alongside demographic data. Statistical analyses included t-tests, Pearson's correlations, and ANOVA to explore group differences, correlations, and interaction effects.
